A Vision To Clear Solutions.
Measurement of Reinforced Concrete Works:
1. The Quantities can be rounded off to the nearest two decimals.
2. Concrete in Structural members, such as columns, Beams and slabs shall each be measured separately.
3. No Deductions shall be made for the following
4. Footings:
Rectangular Volume = L x B x D
Trapezoidal Volume V= H/3 (A1 + A2 + SQRT(A1 + A2) )
Where A1 and A2 is the area of top and bottom rectangles, H is depth of footing.
Total Volume = Rectangular Volume + Trapezoidal Volume
Where V= Volume; h= height;
Measurement of Reinforced Concrete Works:
1. The Quantities can be rounded off to the nearest two decimals.
2. Concrete in Structural members, such as columns, Beams and slabs shall each be measured separately.
3. No Deductions shall be made for the following
- Opening up to 0.1 m2
- Volume occupied by reinforcement.
- Volume occupied by pipes, conduits, sheathing, etc not exceeding 100cm2 each in cross-section. Moulds, drips moulding, chamfers, splays rounded or covered angles, beds, grooves and rebates up to
- 10 cm in girth.
4. Footings:
Volume of concrete = L x B x D for Rectangular and Square footing. For Trapezoidal Footing, Volume of Concrete is calculated in two parts. Bottom Rectangular portion is calculated separately and Trapezoidal volume is calculated separately.
Rectangular Volume = L x B x D
Trapezoidal Volume V= H/3 (A1 + A2 + SQRT(A1 + A2) )
Where A1 and A2 is the area of top and bottom rectangles, H is depth of footing.
Total Volume = Rectangular Volume + Trapezoidal Volume
Where V= Volume; h= height;
5. Columns: Columns shall be measured from top of Column base to underside of first floor slab and subsequently from top of floor slab to underside of floor slab above. In case of Columns for flat slabs, flare of column shall be included with column for Measurement.
6. Beams: Beams shall be measured from face to face of columns and shall include haunches, if any,between columns and beams. The depth of beams shall be measured from bottom of slab to bottom of the beam except in case of inverted beam where it shall be measured from top of slab to top of beam.
7. Pedestals: Pedestals is measured from top of Footing to top/ Bottom of plinth beam depending on site conditions. If measured up to bottom of Plinth beam then Ground floor column can be measured from Bottom of plinth beam to underside of slab. The Height of Pedestal can be arrived from levels of footing and plinth beam. The Height shall be crosschecked with site also
